Radwanul Hasan Siddique

[edit]

Radwan has been inspecting the optical active nanostructures/photonic crystals on biomimic butterfly scales theoretically using FEM simulation and high resolution optical microscopy. Meantime, he is working on the fabrication of the scales to mimic all possible features of original butterly structures for various applications like high iridescent self-cleaning and environmental friendly light displays, cosmetic and fabrics, thermal and vapor sensors, plasmonics, solarcells etc. He is highly motivated and enthusiastic person. He loves to enjoy work whether drilling hard with research or chatting with family and friends. Only philosophy of life, 'enjoy your work, then it will be automatically easier for you'.

He is interested on physics at nano scale: Modeling & Fabrication, Application of Nano and Bio-Photonics, Biomimetics and bio inspired application. Currently he is a PhD researcher at Helmholtz Institute of Microstructure Technology (IMT), Karlsruhe Institute of Technology (KIT). Radwan joined the Karlsruhe Institute of Technology (KIT) within the Erasmus Mundus MSc program 'EuroPhotonics' which is jointly run with Institute Fresnel in Marseille and several institutions in Barcelona sponsored by EU Commission. After graduating with a Bachelor in Electrical and Electronic Engineering from Bangladesh University of Engineering and Technology (BUET), Bangladesh, he has been selected for the program in a rigorous selection procedure with only 18 intakes out of more than 600 applicants. Radwan performed very well in the master program and graduated with “very good”, the best mark available at KIT. Furthermore, Radwan is a very active and valuable member of OSKar which is the SPIE and OSA student chapter of Optics & Photonics students in Karlsruhe. He has shown leadership as an organizer for several events during 2013-14. He is currently acting as a vice president of the chapter and continuously demonstrating his potential to become a true leader in the Optics & Photonics field.
